FREDERIC SCHAEFEB, F PITTSBURGH, PENNSYLVANIA BRAKE BEAM HANGER BRACKET Application filed May 4,

To prevent. this condition, the hangers have been formed'in the shape of a closed loop with a relatively long section swinging on a corresponding supporting surface, and

recently the American Railway Association has specified such construction.

The object of my invention is to provide an improved bracket for such a hanger by utilizing a removable bushing which may be replaced when excessive wear has taken place. The use of such a bushing has been previously suggested but so far as I am aware such bushings have always been so assembled with the bracket on which they were mounted with the hanger which they sup port that it was impossible to remove the hanger without also removing the bushing, and it is a further object or" my invention to produce a renewable bushing which will permit the brake hanger to beremoved without necessarily disassembling the bushing from its bracket.

In the preferred form of my invention I attain a still further object, namely, that of preventing the removal of the hanger from the bushing and bracket unless the hanger is rotated to an abnormal position, such as would not be assumed at any time during the functioning of the hanger.

In the accompanying drawings which 1 4B illustrate my -invention Figure l is an elevation of the side of a truck side frame provided with a bracket for a brake beam hanger and showing the application of my bushing and a hanger supported 60' thereby.

1927. Serial No. 188,685.

Figure 2 is an enlarged detail vertical section through the bracket, bushing, and

hanger.

Figure 3 is a vertical transverse section on line 33 of Figure 2.

Figures 2 and 3 illustrate the preferred embodiment of my invention.

Figures 4; and 5 are, respectively, side views and end views of a bracket and associated parts and illustrate a modification of my invention. 1

. Figures 6' and 7 similarly illustrate another modification of my invention.

Figures 8 and 9 similarly illustrate another modification of my invention.

Figures 10 and 11 illustrate still another modification of my invention.

Figures 12 and 13 illustrate another modification of my invention.

Figure 14 indicates the general shape of all the forms of the bushing before the same is assembled with the bracket.

In the underframe structure illustrated in Figures 1, 2, and 3, the truck-side frame 1 'is shown as comprising a one-piece casting including an integral bracket 2 having spaced jaws 3 and 4 forming an open-ended recess with an open side. Seated in this recess is an open-ended and open-sided bushing 52 substantially U-shaped in cross section. Lugs 6 on the jaws 3 and 4 and correspond ing projections in the legs of bushing 13 form interengaging elements which resist movement of the bushing out of the rece formed by the jaws. Bushing 5 is preferabl t J rormed of yielding material with diverging legs as shown in Figure 14, and thelegs are compressed when the bushing is inserted between {)aws 3 and 4 whereby the elasticity of the ushing causes its legs to en age withthe lugs 6 on the jaws. The ends 0 bushing 5 are flanged outwardly as indicated at 7 w ereby the ushing is more securely retained in the recess and the edges of jaws 3 and 4 are protected against wear from frictional contact with the hanger 8.

The depressed portions 9 of the bushin legs approach each other to form a restricted passa s between the ban er seat at the inner end or the bushing andEbo open side of the ioo bushing. The upper portion of hanger 8 which is seated in the bushing is preferably formed of a flattened or ovoid cross section, the longer axis of which is greater than the width of the restricted passage formed by depressions 9, but the shorter axis of which will permit the hanger to be removed from the bushing when the hanger is rotated to the dot-and-dash position indicatedat 10. It will be understood that this dot-and-dash position is one which the hanger cannot assume while it is supporting the brake beam in the usual manner. If the diameter of the bar is no greater than the distance between depressions 9, it will be seen that the hanger may be removed through the end of the bushing as well as through the side of the bush- As an additional precautionary measure, a pin 11 may be inserted through jaws 3 and 4 and bushing 5.

It will be seen that upon removal of pin 11, if the latter is used, the hanger may be removed from the bracket without disturbing the bushing. Hence there will be little likelihood of the bushing being misplaced during adjustment or repairs on the brake beam or other parts.

If at any time, however, the bushing is unduly worn, the same may be easily removed and replaced with a new bushing. In this form of my invention, it will be noted that the bushing may be reversed top for bottom and its life thereby increased.

In the structure illustrated in Figures 4 and 5, the bushing 12 is provided with lugs 13 which extend into suitable depressions in jaws let and the ends of the bushing do not have the flanges provided on the bushing illustrated in my preferred form. I/Vith this mounting the hanger can be removed from the bushing without rotating it from its normal position and this .may be found desirable in some applications. The looking pin 15 may be used or not as desired.

In the modification illustrated in Figures 6 and 7 the legs of the bushing 16 are seated in a depression formed in the jaws 17 and suitable lips 18 on the latter retain the bushing. With this form of the bushing and jaw it will be necessary to remove the bushing endwise rather than through the open side of the jaw. The hanger 19, however, may be rotated and removed through the open side or end of the jaw without removing the bushing. In the modification illustrated in Figures 8 and 9, the legs of bushing 20 are straight and are seated in depressions in the jaws and at their ends are provided with flanges 21 which engage the outer faces of the jaws near the open side of the recess.

Inthe modification illustrated in Figures 10 and 11 the bushing 22 also has straight legs engaged by suitable lips 23 on the ends of the jaws. This construction is perhaps the simplest form of my invention.

In Figures 12 and 13 the bushing 24: is provided with projections 25 which resist movement of the bushing lengthwise of the recess between jaws 26 but do not resist movement of the bushing through the open side of the recess between the jaws, such movement being resisted by the engagement of the lips 27 with the ends of the legs of the bushing.

In each of the modified forms of my invention, one or more features of the preferred embodiment are retained, and all of the forms attain the general object of my invention, namely, the provision of a renewable bushing which is not necessarily disassembled with the bracket when the brake hanger is removed from the bracket.

Obviously many other modifications in the detailed structure of the bushing may be made without departing from the spirit of my invention, and I contemplate the exclusive use of such variations as fall within the scope of my claims.
